The door assembly A is disclosed in Figs. 1 and 8 as being equipped with the felt, cardboard or similar member |21 which extends across the inside surface of the wall portion of the housing member and the plate- I6, where such a plate is used, together with the fabric or upholstery member |28 suitably secured to the cardboard member |21 and provided with the bead portion |29 and the pocket member I 30.

In operation and with the door assembly A in its normally closed and unlocked position, as disclosed in Fig. 3, the movement of the handle member 18 in a clockwise direction will rotate the rollback member 49 which will cause the cam portion 65 to engage the surface 61 of the arm 68 of the dog member 36 which will move the plate 38 together with the lock plunger 28 to the positions disclosed in Fig; 4 in which the end of the plunger 28 is withdrawn from engagement with the surface 33 of the catch member 9 to the position |3I Fig. 4, which allows the door assembly A to be pivotally moved to an open position as desired, the connecting member pivotally moving relative to the dog members 81 and 36.

When it is desired, with the door assembly A in a closed position as disclosed in Fig. 3, to lock the door assembly A, the operator may insert the key 15 in the key lock mechanism 16 and by turning the key 15, the mechanism of the key lock mechanism 16 which is operatively connected with the shaft member 89 will rotate the shaft member 89 together with the dog member 81 which will move the surface |32 of the extension portion |33 of the dog member 81 to an engaged position with and relative to the ange portion 55 of the plate 38, as disclosed in Fig. 5, and which also causes the connecting member 95 and the dog member 36 to assume the positions disclosed in Fig. 5, and in which positions the cam portion 65 of the rollback member 49 cannot engage the surface 61 of the dog member 36 and therefore the lock mechanism B cannot be operated, the operation of the handle member 18 merely rotating the roll-back member 49 which will be positioned when at rest in indexed positions due to the engagement of the at portions 84 of the spring 8| engaging the fiattened surfaces 48 of the roll-back member 49, the cam portion 65 of the roll-back member 49 being indicated in its indexed positions by the dotted lines 65A, Fig. 5. Also the dog member 81 is adapted to disconnect the outer handle 19 and its roll-back 49 from the plunger 28 by raising the talon 36 out of the path of the roll-back 49 as the dog member is operated to a locking position, as disclosed in Fig. 5, relative to the outer handle 19 and roll-back 49.

The lost motion mechanism between the lock mechanism 16 and the shaft or spindle 89 is disclosed in Figs. 25 and 26.

The lock mechanism 16 is provided with the cylinder 16A which is rotatably mounted and operated by the key lock mechanism, the cylinder 16A having a portion of its side wall cut away to form the shoulders or stops 16B for limiting the movement of the pin 89A which is mounted in the spindle 89 and adapted to turn therewith, the pin 89A allowing the spindle 89 to be rotated by the handle member |02 between the stops 16B without rotation of the key lock mechanism and at the same time allowing the key lock mechanism to be rotated without rotating the spindle 89 through a length of movement of the pins 89A between the stops 16B.

Also the dog member 81 will be in an unlocked position, as disclosed in Fig. 4, relative to said outer handle 19 and said roll-back 49, when said dog member 81 is operated to lower the talon 36 to a position where it may be engaged by the roll-back 4) to operatively connect the outer handle 19 with the plunger 28. Thus it will be noted that the plunger 28 together with the plate 38 may be retracted by the rod I I2 together with the handle member |20 operatively connected therewith, said handle member |20 being located on the inside of the door assembly l, the above mentioned lost motion mechanism between the key lock mechanism 16 and the shaft 89 permitting the dog member 81 to be revolved from its position disclosed in Fig. 5 to that disclosed in Fig. 4 without movement of the key 15.

Also if the operator is on the interior of the body with which the door assembly A is assembled, the extension portion |33 may be operated by means of the handle member |02 and the shaft member 89 to the locking position as disclosed in Fig. 5 with the results as above described relative to the operation of the key 15 and the key lock mechanism 16. It will thus be noted that with the lock assembly B in a locked position as disclosed in Fig. 5, the lock mechanism B may be unlocked from the interior of the body of the vehicle by the leverage and handle mechanism or the lock mechanism B may be unlocked from the exterior of the body of the vehicle by the key and key lock mechanism.

Also it is to be especially noted that with the door and lock mechanisms in their closed and locked positions that it will be impossible for anyone such as undesired passengers, gunmen, etc., to jump on the running board of the vehicle and by grabbing the handle 18, to operate the lock mechanism B to an unlocked position or to break the handle or other operating parts of the door and lock mechanisms because continued operation of the handle member 18 merely revolves same with no further resultant operation of the lock mechanism B, thus providing safety characteristics which protect the operator and occupants of the body of the vehicle from undesired molestation and assault.
